Abstract: |
This paper presents an intelligent mobility criteria
for Cognitive radio (CR) technology. CR technology is a
promising solution to enhance the spectrum utilization by
enabling unlicensed users (Secondary User SU) to exploit the
spectrum in an opportunistic manner. Since unlicensed users
are considered as temporary visitors to the licensed spectrum,
they are required to vacate the spectrum when a licensed user
reclaims it. Due to the randomness of the appearance of
licensed users (Primary User PU), disruptions to both licensed
and unlicensed communications are often difficult to prevent,
which may lead to low throughput of both licensed and
unlicensed communications. When the SU moves out of
coverage of PU, then communication is impossible. Here I
proposed a method to sense the nearest available PU and
hence communicating over the spectrum with minimum delay
and no throughput loss. |
